Burnley midfielder Hannibal Mejbri has accused Preston forward Milutin Osmajic of racially abusing him during Saturday's goalless draw in the Championship at Deepdale.
The match was delayed for several minutes in the second half when the Tunisian reacted furiously to something that appeared to be said to him by Osmajic and spoke at length to referee Andrew Kitchen.
In a post on Instagram, former Manchester United player Hannibal said: "I will not be silent about what happened today. I will always call out racism whenever I hear or see it.
